FILTER Filed. July 17, 1950 INVENTOR ATTOR NEY Patented Sept. 6, 1932 UNITED STATES JULIUS C. MISNER, OF TERRE HAUTE, INDIANA FILTER I Application filed July 17,

This invention relates to a filter for gas, air and the like, the general object of the invention being to provide means whereby the fluid is caused to pass through a liquid and 6 then through perforated plates so that all dust and foreign matter are separated from the fluid, with means for causing the fluid to pass through a considerable amount of the liquid before escaping therefrom and to provide means for retarding the escape of the fluid from the device and to keep the device completely filled with the fluid at all times.

This invention also consists in certain other;

features of construction and in the combination and arrangement of the several parts, to be hereinafter fully described, illustrated in the accompanying drawing and specifically pointed out in the appended claim.

In describing the invention in detail, reference will be had to the accompanying drawing wherein like characters denote like or corresponding parts throughout the several views, and in which Figure 1 is a vertical sectional view through 95 the invention.

Figure 2 is a section on line ure 1.

Figure 3 is a top plan view showing how the inlet and outlet pipes are connected with the cap. V

In these views, the numeral 1 indicates a casing having its bottom closed and its top 22 of Figopen, with exterior threads at the top of the casing and the numeral 2 indicates a cap having a depending flange which is interiorly threaded so that the cap can be threaded on the casing to close the same. A gasket 3 is placed between the cap and easing, as shown. The cap is provided with an enlargement 2 which is formed with oppositely arranged angle shaped passages 4, each of which extends from one end of the enlargement through the bottom of the cap. The outer end of each passage is internally threaded and an inlet pipe 5 is threaded in the outer end of one passage and an outlet pipe 6 is threaded in the other passage. The lower end of the first passage is also threaded to receive the upper threaded end of a vertically arranged pipe 7 which is located in 1930. s rial 1m 468,660,

the casing and which terminates short of the bottom there-of. Perforated plates 8 are ar ranged in the casing and contact the walls thereof and the pipe 7, said plates having centrally arranged holes therein through V whichthe pipe 7 extends. An imperforate plate 9 is carried by the pipe 7 adjacent the upper end thereof and a similar plate 10 is carried by the pipe 7 adjacent the lower end thereof. These plates are of much less diameter than the casing and the plate 9 is of larger diameter than the plate 10. A nonevaporating liquid 11 is placed in the bottom of the casingv and encloses the lower end of the pipe 7. A depression 12 is formed in the center of the bottom of the casing and a drain cock 12 is threaded in the bottom wall 7 of the depression. Thus it will be seen that the air or gas entering the pipe 7 will flow through the first passage 4 and then down the pipe 7 so that this gas or air must pass through the liquid and the plate 10 acts to hold the gas or air in the liquid for some time and it also causes the fluid to come in contact with the entire surfaces of the perforated plates 8.

The gas or air then passes through the perforations and then flows through the outlet passage 4 into the pipe 6. The upper plate 9 retards somewhat the escapev of gas or air and also acts to keep the casing filled withthe fluid. The perforated plates 8 are kept moist by the passage through them of the moisture laden fluid and thus these plates act to remove foreign matter from the air or gas,

though, of course, mostof this matter is removed as the air or gas passes through the liquid. By placing the drain cock as shown,

the liquid can be renewed without interrupting the use of the device.

It is thought from the foregoing descrip- 9 tion that the advantages and novel features of the invention will be readily apparent.

It is to be understood that changes may be made in the construction and in the combination and arrangement of the several parts,

provided that such changes fall within the scope of the appended claim.

What I claim is A gas filter adapted to be connected in and supported by alined flow pipe sections comprising a cap having a depending peripheral flange, a casing screwed within the flange and closed by the cap, the cap being provided upon the top side thereof with an enlargement disposed diametrically of the cap, said enlargement provided with internal passages spaced from each other at their inner ends,

said passages having outer ends at the ends of the enlargement and adapted to be connccted with sections of the flow pipe, and

the inner ends of the passages being at the under side of the cap, a pipe depending from the inner end of one passage and housed within the casing and having the lower end thereof open and spaced above the bottom wall of the casing, a series of spaced perforated plates mounted upon said pipe and disposed across the interior of the casing and imperiorate plates mounted upon said pipe, one

beyond each side of theseries of perforated plates and the upper imperforate plate being of greater diameter than the lower imperforate plate and having the periphery thereof spaced from the inner side wall surface of the casing.

In testimony whereof I aflix my signature.

JULIUS o. MISNER.
